| The STMicroelectronics L9963E is a Li-ion battery monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48 V and higher voltage systems. Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The device can monitor up to 7 NTCs. The information is transmitted through SPI communication or isolated interface.AEC-Q100 qualified Measures 4 to 14 cells in series, with 0 μs desynchronization delay between samples. Supports also Busbar connection without altering cell results Coulomb counter supporting pack overcurrent detection in both ignition on and off states. Fully synchronized current and voltage samples More information: | | Mounting Type: | Surface Mount | Package Type: | TQFP64EP | Pin Count: | 64 | Typical Operating Supply Voltage: | 48 V | Maximum Output Current: | 200mA |
